I've run into an age-old issue but I don’t see any off-the-shelf solutions for. Suppose I have 2 XML documents I want to compare (not diff, just give me yes/no are they equivalent). This is pretty simple to do even with things like ignoring whitespace options etc. Many tools out there, including one I wrote ( http://www.xmlsh.org/CommandXcmp) Now here's the twist … Suppose I want to compare for XSD data model equivalence, not XDM equivalence ? Example. <number>1.0</number> vs. <number>1</number> Without type annotation these are different. they should compare equal. Thus a compare tool should be able to be given a schema and do a comparison and report that these 2 documents are equivalent at the XSD data model level. Has anyone seen anything like this ? Would anyone have a use for it ? (I may end up writing it for my own uses). Not sure how far one can take this before entering murky waters … Even in the numeric cases there are edge cases where comparisons are not well defined (rounding/precision issues on floating point numbers). Then add in things like date/times … But suppose I'm willing to avoid the murky edges and just stick to the obvious cases … shouldn’t be too hard right ? -David ---------------------------------------- David A.
